Affordable St. Lawrence River living, one hour from Ottawa and Montreal.
Residential properties for sale within the City of Cornwall, from REALTOR.ca DDF® listing data, updated every few hours. Asking prices, not sold prices.






Cornwall is Ontario’s easternmost city, set on the St. Lawrence River with the Seaway International Bridge to New York State. It has about 48,000 residents (2021 Census) and sits right on Highway 401, about an hour from Ottawa and a little over an hour from Montreal. That location has made it a hub for distribution, logistics and manufacturing employers.
For buyers, Cornwall stands out for value: detached homes, waterfront access and room to grow at prices that are often well below larger cities. The riverfront parks and the Waterfront Trail make it a favourite with families and retirees alike, and investors like its rental market and duplex and multi-unit stock.
